Yep, the former would surely require lots of work (though maybe not the latter). > > I believe the idea with a PyPy/JS Interpreter is more > interesting, at least from the PyPy perspective. Btw, Possibly, but I advisedly used the adjective "useful" rather than saying "interesting";-) JS's only advantage is one of *deployment* -- browsers have JS interpreters, so you can write AJAX code and dramatically improve the user experience. "Sweating blood" is a charitable description of what it takes, but several examples prove it can work in RL. I just find myself daydreaming that I could do the coding in Python (or almost any other VHLL) rather than JS, that's all;-) > being faster than current JS interpreters is probably > easier than being faster than CPython :-) Yes, good point. > Such a JS-interpreter implementation could be > integrated with browsers allowing JS and Python > directly in the browser. Any Python implementation might be integrated with browsers, but it just seems to take a long time happening (even for Firefox, which should allow it most easily)...;-) > > That being said, it might actually be worthwhile to compile > RPython to Javascript which should be reasonably fast > for small programs.

True, annotation wouldn't help much here (translating among VHLLs). Alex _______________________________________________ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev
